Blender crashes on start- "failed to set 44100 hrz"
You need to set your sound settings from 44k to 48k, here is how:

Before that, my windows version at the moment is version 1909. Windows settings might be changed in the future.


1)Open settings
2)Select "systems"
3)Select "sounds"
4)
5)
6)
7)Apply and close all windows. launch blender.


If works, you may stop here, otherwise if you are stuck on grey screen in Blender:


1) Windows Key + R 
2) type cmd . press Enter .
3) press Windows Key

4)

5) Drag

6) Press Enter and it should work.


That is all I know. 
This minor issues happens a lot when you are using old pcs, laptops or old nVidia card as i know, because new apps might use new settings etc.
